Checklist of the macroalgae of Thau Lagoon (Hérault, France), a hot spot of marine species introduction in Europe

Abstract

A checklist of macroalgae in Thau Lagoon (Hérault, France), based on literature records and new collections, is given. Using present-day taxonomy, 196 taxa and stadia of macroalgae have been identified to date. Sixty of these were no longer found in the samples, 36 were new to the lagoon, and the taxonomic identity of 15 species was amended. Twenty-five new introduced taxa were identified, giving a total of 45 introduced macroalgae for the flora (23% of total).

Cryptic diversity ofUlva(Ulvales, Chlorophyta) in the Great Bay Estuarine System (Atlantic USA): introduced and indigenous distromatic species

“…Ulva pertusa is an Asiatic species, occurring in the North and South Pacific, plus the coasts of South Africa and Europe (Lo´pez et al, 2007;Guiry & Guiry, 2009). Its means of introduction to the North Atlantic is unknown, but it is assumed to have been transferred with Asian oyster aquaculture (Verlaque, 2001;Verlaque et al, 2002;Lo´pez et al, 2007). The species was reported in 1994 off the coast of Brittany, France and in the Mediterranean Sea, where it was previously misidentified as U. rotundata (cf.…”

“…En el Mediterráneo está citada en el Adriático (Giaccone 1978, Ercegović 1980, Córcega (Boudouresque & Perret-Boudouresque 1987, Rodríguez-Prieto et al 1993, Francia (Feldmann 1939, Coppejans 1972, Verlaque 2001), Grecia (Diannelidis 1953, Gerloff & Geissler 1974, Italia (Rindi et al 2002, Furnari et al 2003, Turquía (Cirik et al 1990) (Aleem 1993). La presencia de H. floresii en las costas españolas queda restringida a las provincias mediterráneas desde Alicante hasta Girona y a las islas Baleares, con una única cita en Cádiz, cerca de su localidad tipo.…”

Predicting invasion patterns in coastal ecosystems: relationship between vector strength and vector tempo

“…Imports of 'other oysters' are ongoing and also include live oysters that may be kept in (or close to) the Oosterschelde. These translocations of oysters within Europe are also suspected of not always being reported to authorities (Verlaque 2001), but secondary spread of associated non-indigenous species provides evidence of ongoing transports. A clear example is the red alga Lomentaria hakodatensis, first observed in the Thau Lagoon in the Mediterranean in 1979, after which it was found in Brittany in 1984, and from where it 'jumped' to the Oosterschelde in 2004 (Verlaque 2001, Stegenga 2004).…”
